Thanks, Michael; with that hint I tried a google search on "Asus
Sabertooth FX" + "secure boot" and found a You-tube video showing me how
to do all sorts of tweaking, including disabling secure boot. Tried
that, and now I can boot from the rEFInd CD.
Cheers
Ian

That is secure boot preventing you from booting an unsigned kernel.
You should be able to disable it in the BIOS though some don't label
it as so obviously.

I recently bought a new PC from PC Specialist (the third one I've
had from them - the laptop I'm using to compose this, and an
"entry level" desktop for my wife). The new machine has an Asus
Sabretooth motherboard with a UEFI BIOS.
The first time I booted up the PC, I was too slow to hit the F2
key to go into the BIOS, and it booted into Windows (I'd specified
that I wanted the machine with no OS, but I guess that PC
Specialist installed Windows for the system test). I promptly did
a restart, and this time caught it in time to hit F2 and go into
the BIOS. I was able to change the boot order so that it booted
from the Mint live DVD, stoked up gparted and re-arranged sda to
have the partition layout I wanted (sda1 as 512MB for the EFI boot
partition, sda2 & sda3 as 20GB partitions for root of Linux Mint
and another OS to try out if I fancy it, sda4 as 20GB swap and
sda5 as the remaining 160ish GB for the "visible" home partition
to share between 2 distros. I was then able to install Mint 17 on
sda2.
I then followed the tutorial in Linux Voice issue 2 to set up sda1
as the EFI boot partition and install the rEFInd boot manager. I
hit a rock when I tried to boot from a USB stick with rEFInd on
it, or a CD with rEFInd on it. The error message was: "The system
found unauthorised changes on the firmware, operating system or
UEFI drivers." I have a strong suspicion that this was an
after-effect of the Windows installation which I deleted.
Can anyone suggest a way of removing this Windows contamination,
please?
Thanks in advance
Ian
